Sounds like you've been thoroughly indoctrinated. It's OK, since it doesn't have to be terminal. You feel guilty over your sexuality. That guilt was force-fed to you by the WTS.
Guilt is the WTS's number one weapon. It's also one of the major reasons someone would join/rejoin the JWs. I know from experience. Guilt leads to religion.
My advice would be to sever yourself from any religion/dogma for a while and see what happens. You may learn to be totally self-reliant intellectually, seeing a man-made program of "spiritual food" as the ridiculous sham that it is. Trust me, once you get here you'll never want to leave. Good luck, Scoob!
